Interesting Facts
- IUPAC allotted a temporary name to Dubnium metal as “ Unnilpentium”.
- In the production of Dubnium, thermal gradient chromatography is used.
- Galena mineral contains almost 87% of Lead metal in it, Galena is sulfide mineral.
- The best available source of Lead metal today is by recycling automobile batteries.

Uses & Benefits
- Currently known uses of Dubnium metal are limited to research purpose only.
- It is also used in insecticides, hair dyes and as an anti-knocking additive for petrol. But all these are banned by the government as Lead metal is known for detrimental to health.
